org.apache.xmlgraphics.image.codec.util.FileCacheSeekableStream
A subclass of SeekableStream that may be used to wrap a regular InputStream. Seeking backwards is supported by means of a file cache. In circumstances that do not allow the creation of a temporary file (for example, due to security consideration or the absence of local disk), the MemoryCacheSeekableStream class may be used instead.
The mark() and reset() methods are supported.
This class is not a committed part of the JAI API. It may be removed or changed in future releases of JAI.
